Re: [PSUBS-MAILIST] Sensor Interfacing
Thanks Warren
i'll bear in mind what you have suggested for future use but now i just need
to 'get my feet wet'.
I have initially chosen a BS2 development kit as it looked more user
friendly than the other types i have seen and there seemed to be a fair
amount of modules available that didn't need too much extra circuitry.
personally i like the idea of minimum support circuitry as my design skills
aren't that great.
Initially i only want to learn the basics and use the ROV subject for a
teaching aid.
Do you have the web links for the Rabbit and MSP430 devices that i can check
out when i've run out of steam?
